LEAK 2000
Price unknown (around 1975)
Commentary
The highest quality receiver from Reek.
The complimentary service stage of the power amplifier consists of a pure output-type OCL, and the A-class driver stage uses a constant current circuit, making it resistant to load fluctuations.
A differential amplifier is used at the input stage of the preamplifier to ensure a high S/N and a precise equalizer curve, and a PLL decoder is used in the MPX demodulator of the FM to ensure stable separation.
